To all whom it may concern,.-

Be it known that I, WILLIAM PH'IrPs,.of'-

Milwaukee, inthe county of Milwaukee, and in the State of Wisconsin, have-invented certain new and useful Improvements in Grates for Furnaces, Stoves, 8vo.; Vand I do hereby declarethae the following is a full, clear, and exact description'thereof. l

My invention relates to grates for furnaces, stoves, 85e.; and it eons'istsin certain peculiari-v ties of construction and combination o f parts,

4; and Fig. 6, a transverse section of my prie# ferred form of grate-bar..

Referring by letter to the drawings, Ay represents the ash-box of a furnace having a front extension, A', each side of the latter being interiorly provided with an angular bracket, B, that has a horizontal portion or seat, a, for the adjacent end of a transverse bar, C, and a vertical upwardly-extended portion, b, provided with a horizontal slot, c.

The transverse bar C has each end 'thereof provided with a vertical slot, d, that receives a pin, D, the latter having its respective ends e bent at right angles to come against the sides of the brackets B, as best illustrated by Figs. 4 and 5.

To set the transverse bar C in position, the pins D are turned in the vertical slotsd, so that their right-angular ends e will be horizontal or in line with the bracket-slots. The bar C, being in place on the horizontal portions or seats a of the brackets B, is pushed rearward until the rear ends of the pins D pass through the adjacent slots c in the vertical upwardly- The ends e assume the position shown in Figs. 4 and 5, and the bar O is firmly locked in place.'

'To remove the bar C it is only necessary to turn the pins D so thatv their ends e will regisand then .draw said bar to the front.4

nel with the horizontal slotsit mentar-ets B,

" The transverse bar C is provided withna se-ji ries of bearings, f, for thefront journals, g, lol't parallel grate-bars E, the 4rear journals, l1., of A, v.

these grate-bars having their bearings in the adjacent Wall of the ash-box,.a s illustrated *by full and dott-ed lines, Fig. 1.

`To prevent the grate-bars E from Iget-tingout of place, I provide their frontA journals, g, with collars i, that come against the inner side of the transverse supporting-bar C, as shown byFig.'1.

My grate-bars are preferably made with-a series-of polygonal collars, j, arranged a't-suit-l able intervals and cast in 'one piece with the cave, as best illustrated byFig. 6. j

To the journals o'f the grate-bars E, in front of the transverse supporting-bar C, are keyed sprocket-wheels F, ,on/which is operatively arsolid central part-of said' bars, 'the polygonal 4 faces of these collars being-also preferably conranged a drive-chain, G, a transverse guardpiece, H, being secured to the ash-box exten- ,sion A', as shown 'byliig. 2,l tozpreventsaid chain from slipping ot the'sprocket-wheels.

The extreme outer grate-bars E have their front journals, g, provided with extensions g',

that are designed toe-'register lwith suitable openings lin the door I`bf the ash-boit, and

each of these journal-extensions has a socket,

' k, to receive a suitable crank (not shown) by .which to operate the entire grate Iffon'nd more desirable, the j carnal-extensions gfinay,

besimply squared for the purpose' of receivj ing a suitable crank. The front journal onl`y of the center grate-bar may be extended and only. on account of its convenience, but for `provided with a crank-socket; but for large -grates the construction described in the preceding paragraph yis deemedpreferablefnot,

the'reason that the drive-chain G is kept taut Athroughout its length while the grate lis being' f operatechand hence there is chain buckling. If desired, lbut one of` the extreme outer noliability otfsaid grate-bars may have its journal extended and provided with a crank "-socket;,but vIhave j j v Ico and prefer such construction forthe sake of -1 g the convenience it aordsthe operator.

shown both the outer vbars thus constructed,

It is not absolutely necessary that each of the grate-bars be provided. With a sprocket wheel, and, if found desirable, I may at times omit some of these Wheels-say every alternate one thereof-thereby having some of saidl bars stationary and the. others capable of being revolved.

Instead of omitting some of the sprocket wheels I may arrange them loose on theirjournals as supports for the drive chain; but it will be understood that any or all of the gratehars constructed to be engaged by a crank have their sprocket-Wheels fast thereon.

By the construction above described it will he noticed that the loose gratebars are all revolvod in the same direction and that one side of cachbar carries down the ashes While the other side forces the coal back, thereby effecting a saving in feel. The 'grate-bars may hc revolved in either direction or alternately back ,and forth, as the operator may prefer; and a peculiar advantage obtained by my grate is that the draft is not impeded and the agitation may he regulated to dump a greater or less quantity of ashes.

, It will be noticed that the effect of the bars in luy-invention is the same at all times, no matter What position they maybe in, and each two adjacent bars are always in the same relai tive position. l

,Having thus fully described my invention,

what 1 claim as new, and desire to secure by Letters Patent, is

1. A grate comprising a series of parallel bars and a front supporting-bar therefor, the latter having its ends provided with Vertical slots, in combination with anglar seats for said ends of the transverse bar having vertical upwardly -extended portions provided with horizontal slots, and pins having right-angular ends and arranged to engage theslots of said transverse bar and seats, substantially as and ior the purpose set forth.

2. The combination, with a furnace ash-box having its sides interiorly provided with an gggu'lar brackets, of a transverse bar having its ends detaehabl y secured to the brackets, a series of parallel gratebarsjournaled in a wall ofthe ash-boX,:1-nd the transverse b:.1r,sprockct Wheels fast on the front journals of thegratebars, a drivechain arranged on the sprocket wheels, and one, two, or more of said grate bars extended outward and shaped to engage a crank, substantially as set forth.

In testimony that claim the foregoing' I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
